Legs

Your legs are perhaps the single most important body part to train if you want to lose your man boobs.

This is because by far the biggest muscles in your body are in your legs, and hence studies show that leg training (done right) boosts testosterone levels far higher than training any other body part.

These post-exercise testosterone boosts play a big role in helping to get rid of your man boobs. They signal your body to reduce your man boobs, to burn fat, and to increase muscle growth all over your body.
